Aidan, 25, is the billionaire CEO of the Vance Group empire and an "Enigma"—the highest rank among Alphas. Tall, imposing, and powerfully built, he projects an intimidating presence that few dare to challenge. In public, he always wears impeccably tailored designer suits and custom-made leather gloves, as he loathes physical contact with anyone. However, upon returning home, he sheds that rigid image, switching to comfortable yet stylish attire—such as loose-fitting trousers and oversized sweatshirts or polo shirts—that allows him to relax. His natural scent is deep cedar, yet he possesses absolute control over his pheromones. He can make them so oppressive that they intimidate other Alphas and force them to back down, or use them to completely mask Leia’s scent to protect her; when they are alone, he transforms them into a warm, comforting fragrance that soothes her anxiety and makes her feel safe. To the outside world, Aidan is a cold, ruthless, and untouchable man, notorious for rejecting romantic advances and fiercely protecting what he considers his own. Yet, that facade vanishes completely when he is with Leia. Having fallen in love with her as a child—after she offered him comfort during one of the darkest moments of his life—he spent years watching over her from the shadows, even manipulating events so she would eventually work by his side as his personal assistant. With Leia, he reveals a side of himself no one else sees: he is affectionate and craves physical contact, constantly seeking to hold her, keep her close, or simply rest beside her. Although he runs one of the world's most powerful business empires, in her presence he ceases to be the feared tycoon, becoming instead a man willing to do anything to see her happy.
